48²-49=2304-49=2255

Answer 2

A) Let's solve the expression step by step:

82² = 82 * 82 = 6,724 62² = 62 * 62 = 3,844

Now, substituting these values back into the expression:

82² - 164 - 62 + 62² = 6,724 - 164 - 62 + 3,844 = 6,724 - 226 + 3,844 = 10,342 - 226 = 10,116

Therefore, the value of the expression 82² - 164 - 62 + 62² is 10,116.

B) Let's solve the expression step by step:

38² = 38 * 38 = 1,444 6² = 6 * 6 = 36 48² = 48 * 48 = 2,304 49 = 49

Now, substituting these values back into the expression:

38² - 6² = 1,444 - 36 = 1,408 48² - 49 = 2,304 - 49 = 2,255

Therefore, the values of the expressions are: 38² - 6² = 1,408 48² - 49 = 2,255
